Sikhote-Alin Coarsest Octahedrite

On February 12, 1947 a blazing fireball estimated to mass 70 to 100 tons exploded 3.6 miles above the Sikhote-Alin Mountains north of Vladivostok, Russia. When the main detonation occurred, Sikhote-Alin had already shed most, if not all, of its cosmic velocity.

As a result of this late detonation, many of the resulting fragments were not traveling fast enough for atmospheric friction to cause additional ablation and Sikhote-Alin specimens can be found in two distinct forms: the traditional iron meteorite with smooth surfaces and regmaglypts, and a shrapnel form that demonstrates the explosive tearing and shearing forces encountered as the iron bolide shattered at low altitude.

Sikhote-Alin specimens are currently available in many forms and exotic shapes that illustrate the classic characteristics of this unusual and important meteorite.
